(Cl. 'i4- 502) 12 Claims.

This invention relates to improvements in remote control devices for brakes and other remote controlled parts.

The main objects of this invention are:

First, to provide a control device'which is well adapted for use in controlling brakes and is strong and rigid, and one in which the parts are effectively supported in their coacting relation.

, Second, to provide a control device in which the adjusting member is substantially smooth so that there are no parts with which the operator or the operators clothing is likely to become engaged.

Third, to provide a structure of this type which parts in longitudinal section on a line corresponding to 'line 2-2 of Fig. l.

Fig. 3 is an enlarged fragmentary view partially in longitudinal section on a line corresponding to line 3-3Vof Fig. 4 with certain parts in full` lines- Fig. 4 is a transverse section on a line 4- 4 of Fig. 3.

Fig. 5 is a transverse section on a line 5-5 of Fig. 3.

In the accompanying drawing, I represents a part of a motor vehicle or other support on which the bracket 2 is mounted. The supporting member 3 is of channel section and secured at its forward end to the bracket 2 preferablyby welding as indicated at 4. The support member `3 is provided with forwardly facing ratchet teeth 5 on its flanges and terminates in an integral tubular portion 6 at its rear end externally threaded to receive one or more nuts I for facilitating mounting on a support not illustrated.

The adjusting member 8 is of channel section and disposed to face the support member and is slidable therein andthrough the opening 9 in the :bracket 2. At its forward end the adjusting 2 member is provided with a grip Ill having a socket II receiving the endof the adjusting member and secured thereto as by staking indicated at I2. At its rear end the adjusting member is provided with inwardly turned lugs I3 adapted to receive between them the coupling head I4 of the flexible transmission member I5.

' The head I4 is provided with a groove I6 with which the lugs I3 engage, the lugs being conformed at Il to receive the reduced portion of the head and retain it in assembled relation. To facilitate assembling of the parts, the web of the support member is provided with a suitably shaped slot I8 through which the head may be is very easily and quickly assembled both in the passed and then SWllng upwardly and engaged assembly of the parts and complete assembly. between the lUgS, the adjusting member having Fourthr, to provide a control device having been previously lJOSOned in the Support memthese advantages which may be very economicalber to permit this engagement. 1y produced. The transmission member I5 is provided with Objects relating to details and economies of a sheath I9 having a tubular adapter 20 at its the invention will appear fromv the description to front end. This adapted has a portion 2| adaptfollow. The invention is dened and pointed out edtto be inserted in the tubular portion 6 of the in the claims. y support member as shown in Fig. 1 and with the A preferred embodiment of the invention is shoulder portion 22 abutting the rear end of the illustrated in the accompanying drawing, in tubular pari? 5 The adapter has a bendable lug which: 23 at its front end which is bent into retaining Fig. l is a vfragmentary side elevational View engagement With the Support as is shown in Figs. of-acontrol device embodying my invention, parts 1 and 2. This arrangement enables the very thereof being shown in longitudinal section. rapid assembling 0f the tre-IISHISSOII elements Fig. 2 is a fragmentary plan view with certain 30 with the supporting and operatingparts. The

transmission member I5 is provided with a terminal 24 for facilitating its attachment to the operated part.

The detent 25 is of U-section and is provided with teeth 26 adapted to coact with the ratchet teeth 5 of the support member. The detent is pivotally mounted on the adjusting member by means of the pivot 2l arranged through the arms of the detent and through the ilanges of the adjusting member, see Fig. 4. The detent is biased by the blade spring 28 which has ears 29 engaging the pivot 21 and is provided with an inturned tail portion 30 engaging the adjusting member. The detent is released by means of the reciproeating control rod 3l which is provided with a finger piece 32 projecting from the grip. The coil spring 33 acts to return the control rod. At its inner end the control rod is provided with a cam 34 coacting with the finger 35 of the detent which projects through a hole 35 in the adjusting member. The spring 37 is arranged within the adjusting member to bear on the control rod to prevent rattling thereof and also adding some frictional resistance.

To further prevent rattling and provide frictional resistance to adjustment, the U-shaped or stirrup-like friction member 38 is provided, the arms 39 of which are engaged by the pivot 21. The bight 40 of this member is upset into frictional engagement with the web of the support member 37, This upsetting operation can be performed after the` parts are assembled to secure the desired frictional engagement and to pre; vent rattling. The stop 4| engaging the slot 42 in the control rod 3| limits the movement of the control rod. The springs 43 on the bracket engage the sides of the adjusting member to still further prevent rattling. Y

With the parts thus formedandarranged they may be very rapidly assembled and the structure is very strong and rigid and there are no ekposed parts which might injure the operator. The ease of assembly is a very decided advantage. In the final assembly the adapter of the cable or transL mission member sheath is inserted into the tu-v bular portion o f the slmporti'nerx'lber` and secrd by the lug 23. The cable or transmission'inernber head is dropped through the'cleajrance rslot while 'shader-ent is Vengaged with suitable' teethqn this embodiment the third frein the rear e. `In vthis position the head can be between the lugs on the adjusting member and the lugs closed or staked uponthe head member. This enables the the'assembling o f thepar'ts without the necessity oihandling all of them as they are p ut together. The assembly of the transmission elements can be readily performed after the other parts are assembled and this avoidsthe necessity of handling long and unwieldy parts. Another feature of importance i's that there are no rotating parts. While the 4applicants control is easily manipuliated by an adult, it is unlikely thata child would orl could actuate the release push button nnger piece which is normally under considera-ble pres- Sul'e;

I haveil'lustrated and described my invention in Ya highly practical embodiment thereof. I have not attempted to illustrate various adaptations which I contemplate las it is ,believed this dis-'- closre will enable those skilled in the art to "enibody or adapt my invention as "may be desired.
